So wow...if you read the update to Moe Berg's Wikipedia page you get this -
In April 2016, it was announced that American actor Paul Rudd will portray Berg in an upcoming biographical drama film called The Catcher Was a Spy, based on the book of the same name. The film will be directed by Ben Lewin and is likely to be released in 2017.

I like Paul Rudd, it will be interesting to see how they portray him as Rudd isn't the most serious actor. I'd more excited if say, Tom Hardy was playing him or someone like that. Either way, can't wait to see it.
